IMPROVEMENT IN SASH-FASTENERS.

Specification forming part of Letters Patent No. 208,821, dated Octoberil, 1878; application filed July 22, 1878.

To all whom it may concern.'

Be it known that I, BENJAMIN B. HUGHES, of Portage, in the county ofColumbia and State of Wisconsin, have invented certain new and usefulImprovements in Sash-Bolts; and I do hereby declare that the followingis a full, clear, and exact description thereof,which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification, and in which- Figure 1 is a sectional elevation ofmy improved sash-holding bolt, and Figs. 2 and 3 are detail views ofthesame.

Corresponding parts in the several gures are denoted by like letters.

This invention relates to certain improvements in sash-holding bolts orfasteners for windows, and is characteristic for its simplicity,effectiveness, and durability; and it consists in the employment, inconnection with a bifurcated plate-spring, of a bolt having lateralnotches to receive the prongs of the bifurcated portion of the spring,beyond which lateral notches of the bolt toward its inner end the boltserves to hold the sash or window, substantially as hereinafter morefully set forth.

In the drawing, A refers to a portion of the window frame or sash,through which is made or bored a hole, a, extending through said sash ina line about parallel with the surface of the window-panes. B is thebolt in` sorted in said hole a in the sash, with one end provided with ahead or knob for convenience in grasping and operating it, and the otherend projecting therefrom and entering any one of a series of aperturesin the frame within which the sash moves and is held.

C is a at spring, made preferably of the best spring metal or steel,fitting within a mortise in the sash A, to which it is fastened at oneend by a screw or other suitable means. Its upper end, it being arrangedperpendicularly, is bifurcated or provided with arms c c, which enterlateral notches or recesses d d, cut or otherwise formed in the bolt B,to connect the spring and bolt detachably together.

By pulling the bolt outwardly its inner end will be retracted from thewindow-frame, or rather from the coincident aperture therein, the springyielding with the direction in which the bolt is pulled, when the sashor window can be raised or lowered, as may be required, and held at th'edesired point by the springing of the bolt into the proper aperture orby the holding of the bolt and allowing it when released to springintothe aperture that will suit the height to which it is desired toraise the window. In lowering the window it may be likewise held at anydesired point below by similarly operating the bolt. When completelydown, the windowis locked in position by the bolt and its spring.

My invention, it will be discovered from the foregoing, dispenses withthe use of coiledwire springs, cams, &c., and is cheap, simple, durable,and effective, and easy to make and apply to the sash or window.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- The sash-fastener consisting of thebolt B, provided a short distance from its inner end, or that end neXtto the sash, with lateral notches d d, to enable the bolt from saidnotches toward said end of bolt to form a means for supporting the sash,in combination with the iat or plate spring C, bifurcated at its upperend, as at c c, to embrace the notched portion of the bolt B,substantially as shown and described, for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto aixed mysignaturel in presence of two witnesses.

BENJAMIN B. HUGHES.
